Because chemical names vary significantly, chemical name searches are frequently inconclusive. For this reason, our search engine is designed to provide a nested result.

For example, if you are searching for a pyrimidine and do not know its CAS No., it is preferable to simply enter PYRIMIDINE. The resulting search provides a listing of all available entries bearing the nested name PYRIMIDINE.

A search of the nested name DIOL results in a similar listing of all available Diols, etc.
